YelloWho puts your live Geotab driver roster into your whole team's phone contacts — so when a driver calls dispatch, safety, or the office, their name and current vehicle appear on screen. Connect a View-only MyGeotab service account once: YelloWho reads drivers, phone numbers, and current vehicle assignments (via DeviceStatusInfo) strictly read-only, and syncs them to each teammate's Microsoft 365 or Google contacts and to NetSapiens-based office phone systems every 15 minutes. Driver switches trucks? Every phone updates itself. A separate "Drivers" contact list is created — personal contacts are never touched — and Geotab groups can filter which drivers each teammate sees. No spreadsheets, no "who is this?", no manual phone books. Self-serve 30-day free trial at yellowho.com.
